Abstract

PURPOSE: To reduce the production cost and also to enhance reliability by forming a bottom ring from an even plate material which has nearly uniform thickness measureed from its outer periphery to its inner periphery and providing a guide vane lower stem bearing in this plate material.
CONSTITUTION: A bottom ring 26 is formed by using an even plate material which has nearly uniform thickness measured from its outer periphery to its inner periphery, and a lower stem bearing of a guide vane 16 is arranged in this material. By this mechanism, its construction becomes simple leading to a reduction of its production cost and a welded portion can be spared at the same time, hence its sufficient rigidity and strength can be provided, leading to an enhancement of the reliability.
